When I used the teacher's code to practice, the same code and path were used, but the system prompted the template "template file does not exist". The following path is the view folder under the TP project, not the view folder under the application. Moreover, the view class folder has been changed to lowercase and underlined. The official manual also writes the path under the tp project. I would like to ask the teacher, is this an additional configuration in your course? Or is it caused by other reasons. How should I configure it correctly? Thank you for your reply.

Error message: Template file does not exist: C:\myphp_www\PHPTutorial\WWW\tp\view\index\view_test\demo1.html
